4 cards from this section. Quick, good the night before a test.
What is the charge of a proton?
Think about the particle's role in the nucleus.
How many neutrons does Carbon-12 have?
Subtract the atomic number from the mass number.
What is the charge of a neutron?
Consider what is meant by 'neutral'.
Protons determine the atomic number of an element.
Recall the definition of atomic number.
If an atom has 10 protons and 12 neutrons, what is its mass number, and what element is it?
Remember to add protons and neutrons for mass number.
Carbon-12 and Carbon-14 are both isotopes of carbon. If you needed to create a sample with a specific ratio of these isotopes, how would you calculate the necessary amounts?
Think about how isotopes relate to neutron count while maintaining the same proton count.
